HelloPharmacist Scorecard of Raspberry Leaf by Cedar Bear

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 10, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (0.50 mL) without saying how much of each component you get.

Cedar Bear Raspberry Leaf is a liquid made from one active ingredient: red raspberry. The product is preserved with USP Grade Vegetable Glycerine and purified water as inactive ingredients.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Red Raspberry product and its label doesn't state a use — see Red Raspberry's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold doesn't establish that red raspberry leaf works for aging skin, heart disease, respiratory infections, congestive heart failure, or diabetes—all ratings are insufficient to say either way. If you're considering it for one of these uses, talk with your doctor or pharmacist about whether the current science supports it for your situation.

The evidence, ingredient by ingredient Red Raspberry

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Red raspberry leaf is generally well tolerated by most adults, though safety data is limited. The most common side effects from oral use are diarrhea, gastrointestinal upset, and stomach pain—but these don't typically happen at normal doses.

One occupational case of asthma-like symptoms (wheezing and shortness of breath) was reported from inhaling raspberry powder, though that's not how this liquid product is used. For pregnancy, the safety data shows conflicting ratings—some sources call it likely safe, others possibly safe, and some flag it as likely unsafe.

Because the evidence isn't clear-cut, use it in pregnancy only under your doctor's guidance. There isn't enough reliable information to know whether it's safe while breastfeeding—talk with your healthcare provider if you're nursing.

Side effects, ingredient by ingredient Red Raspberry

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Red Raspberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 135 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check your blood thinners (anticoagulants and antiplatelet drugs like warfarin and aspirin) and insulin before taking this product—both have Moderate-severity interactions documented. Use the medication checker on this page to verify your exact drugs.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Red raspberry leaf is generally well tolerated but comes with Moderate-severity interactions if you take blood thinners or insulin. If you're on either of those medications, check with your doctor or pharmacist before starting.

Pregnancy and breastfeeding safety aren't fully established, so discuss it with your provider beforehand if you're in either situation.

Anticoagulant/Antiplatelet Drugs

Theoretically, taking red raspberry leaf with anticoagulant/antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that red raspberry leaf extract has antiplatelet activity and enhances the in vitro effects of the antiplatelet medication cangrelor. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Insulin

Red raspberry leaf might reduce glucose levels in patients being treated with insulin.
In one case report, a 38-year-old patient with gestational diabetes, whose blood glucose was being controlled with medical nutrition therapy and insulin, developed hypoglycemia after consuming two servings of raspberry leaf tea daily for 3 days beginning at 32 weeks' gestation. The patient required an insulin dose reduction. The hypoglycemia was considered to be probably related to use of red raspberry leaf tea.
